A meta-analysis of species richness and restoration outcomes globally.

Species richness is a fundamental component of ecological research including restoration. Managing for enhanced native species richness in restoration is a powerful goal and outcome; nonetheless, local species richness can also be used as a mechanism to decide on the lands to acquire, protect, and restore. Here, a meta-analysis was used to test the hypothesis that local species richness is a viable consideration in predicting varied restoration outcomes as identified by primary researchers in drylands.物种丰富度（Species richness）是包括生态修复（restoration）在内的生态学研究的核心组成部分。将提升修复区域内本地物种丰富度作为管理目标，既是生态修复的重要愿景，亦是其理想产出；尽管如此，本地物种丰富度亦可作为决策依据，用于遴选需收购、保护与开展修复的土地。本研究采用元分析（meta-analysis）方法，验证了"本地物种丰富度可作为可靠考量因素，用以预测由旱地生态修复领域一线研究者所界定的多样化修复结局"这一假说。
